Answer: (-4,3)
Explanation: -4=3-7, -4 is the x in the set of coordinates. And 3(-4)= -12 , 4(3)=12. -12 + 12=0 because a positive and a negative of the same number balance out to 0.
The correct answers for these is A,C,D. How I got this was by plugging in (x,y) to the equation. This means that I plug in x and y from the point into the equation and simplifying it to see if it gets the right answer.
